Mineralizing angiopathy presenting as basal ganglia stroke

Mineralizing angiopathy is an important cause of basal ganglia stroke. We describe a case of 4 month old child with normal perinatal and developmental history, who presented to us with complaints of weakness of left upper and lower limb. There was history of fall from swing two days prior to onset of weakness but child remained normal for intervening 2 days. On examination there was weakness of left upper and lower limb with left UMN facial palsy. Intermittent hemidystonia was also observed. MRI revealed right capsuloganglionic infarct while MRA was normal. CT of the brain revealed linear hyper density bilaterally suggestive of mineralization of leticulostriate arteries . Child was started on aspirin and physical rehabilitation. On 6 months of followup child remained well with no reoccurrence. There was improvement in limb functions and normal developmental milestones. Mineralising angiopathy is an important cause for stroke in children after trivial trauma. It should be considered as important etiology while working up for basal ganglion stroke. Reoccurrence are also seen in this disease entity.
